Late 2013 iMac Has The Same Wifi Issues Like The MacBook Air

I'm seeing fairly erratic latency from a new iMac to a new Airport Extreme.
Hopefully a driver issue.
Luckily my iMac will be installed next to my router so no WiFi for me! 
I feel sorry for all those folks dependant on WiFi, it must be a pain especially on a desktop which can be permanently wired up!

Please, be more specific ...why do we expect these problems with wi-fi ac?
I was just saying that ethernet is faster than WiFi, especially in my house which has poor WiFi coverage all round.
Just thought I'd follow up:
I've since added a new Time Capsule to my network, extending the AirPort Extreme network. Since doing so, my ICMP traffic has very low and consistent latency. Nifty.
Note that both devices are the new (2013) versions.
It's kinda cool seeing my new iMac register a 1 Gbit/s link speed...
What is the actual problem? interrupted internet connection? slow data transfer? what? ...each problem has a different root...
Let's say, I have got a Wi-Fi N dual-band router and an iMac with wi-fi ac.
Should I expect any connection or other wi-fi problem? possibly no... If yes?
Should I replace iMac or router? this is the point, correct?
I think we need to find a base of our discussion...

From the first post, totally unreasonable latency.
I .. think I'm experiencing this issue. The next time it comes up I'll try pinging some local devices. I was pinging my server which is at a data center 4 blocks away, getting 500-1100ms with some packet loss. Playing online video games is impossible, various online speed tests I get maybe 1Mbps down and 10 up (meanwhile, my iphone gets 60Mbps down and 10 up).
Restart the router (802.11ac time capsule), no change. reboot the cable modem, no change. Rebooting the iMac always fixes the problem, for a while. Seems to be an issue when it resumes from sleep. I only noticed it starting in the last week or so, I'm not sure why as nothing about my setup has changed.
I haven't had any issues with my 2013 Air wifi from what I can tell (like the issue shown here). I think there are some routers that may not work well with newer 802.11ac chipsets however. I would at least experiment with another router before returning a second iMac.
Now, even though I use wifi a lot and it's certainly convenient, it does indeed suck as a technology when comparing it to a traditional wired connection. Both in terms of performance and security.
I don't even have a lot of signal noise around my house but after years of dealing with all sorts of issues across many platforms I just bit the bullet and dealt with the pain of running CAT6 all throughout the house. Now everything that I can use Ethernet for I do and the difference is simply incredible.

Jealous. Not all of us can bite the bullet and install wiring all over the place (apartment, concrete walls). The wifi is actually just flat out unusable with how broken it is. I have an 802.11ac time capsule, and my old (mid-2011) macbook air, ipad, iphone, half a dozen other devices can connect to it and use it just fine. My flagship computer, the computer I use the most every day, I can barely browse the web on wireless. Hell, my bathroom scale has no issue getting on the wifi all the way on the other side of my admittedly tiny apartment.
That said, my iMac is 10 feet away from the time capsule so until Apple fixes their crap, I guess I just have to deal with having the clutter of two wires on my desk (super first world problem haha).
Here are some screenshots.
This one is my mid-2011 macbook air, pinging an interface on the time capsule, connected to the 5GHz network:
now the imac, connected to that same network. The part at the end where the ping times drop are when I plugged in an ethernet cable.
Forcing the iMac to connect to the 2.4GHz SSID, i.e. 802.11n, doesn't change anything. Avg ping 388ms, 5.3% packet loss over 10 minutes.
The weird thing, at least for me, is that this problem is recent. I've had this iMac for more than a month, and this has only become an issue in the last week. I've had the time capsule for probably 3 weeks, I got it to experience AC speeds but also because my older router running dd-wrt didn't have any ipv6 support.
i pulled out the old router and connected to that to test. Not great

Tried to boot into safe mode and check it ?
Usually when I'm unsure if it's a hardware or software issue, bootcamp can tell everything. You will know if it's your driver, your card or your router.
works great in windows 8.1. too bad windows is.. not why i dropped cash on this imac
gah apple needs to fix these drivers.

Great, so now we know it's either a driver issue or a problem with your OS.
Have you tried a Clean install ? That would be the last resort
Just stumbled on this thread, as I am thinking about buying my first mac (looking at the 27" new iMacs). Is there an known issue with the wifi on these? I'm also an apartment renter and will be here no more than another year or 2, so I'm not about to go drilling holes and stringing cable from the downstairs modem to my bedroom where the computer will reside so I will be needing good wifi.
this is a clean install from a day or two after mavericks release (was on developer preview before). I can definitely try that, though restoring my user data from time capsule took ages last time I tried that --may have been because of this issue, i'll string a cable across the room when I try again.

I wouldn't say there are any widespread issues. These

Is this Win8.1 on your Mac, or on a PC?
on my mac, boot camp
edit: rebooted with cmd+r, ran terminal.app from there, same issue.

I'm just going to flat out say it, is this a ******** joke?
There are a MYRIAD of reasons that everything you're saying is nothing but luddite, ignorant garbage. I only wish someone had stood behind and knocked the keyboard out of your hands before you could type any of this arrogant and idiotic drivel.
For one, not all of us own our own homes. Guess what: I can't exactly knock a few holes in the wall and wire some cable. Even if I could, I should be able to use the features of my computer, not knock walls down to compensate for buggy engineering.
Which brings me to another reason this better be a series of troll posts: sure, wireless isn't going to be as infallible as a wired connection, but this is clearly a hardware or firmware (or software) issue, not the normal operation of a wireless card. There's been definitive evidence that there is something going wrong. It's downright stupid that you're choosing to ignore this and continuing to berate people for expecting their wireless to work as well as it has for the last five years.
I personally have been running into this issue with my new 2012 MacBook Pro Retina 13. On my 2012, the wireless latency is great, and I can get throughput as expected. On the 2013? These issues pop up. It's not like I'm going to wire an ethernet port under the kitchen table, on the counter, next to my bed, on the back porch, in the bathroom and under every seat in the living room..
Please either get out of this thread, or start talking about the issue and stop being a nuisance to everyone who wants to get this issue solved.
My contribution, I'm definitely seeing an issue. I've noticed performance problems in the past, but figured it was internet issues and it would resolve itself. My Mac Pro didn't seem to be having any problems, which I thought was odd, but I let it slide. When I saw this thread, I brought out the ping and low and behold:
This is about four feet from my 802.11ac Airport Extreme. My 2012 macbook? No issues.
for what it's worth, the
trick (replace with the IP of your access point) from the massive apple forum thread (https://discussions.apple.com/thread/5100655?start=1860&tstart=0) seems to take care of this. not a great solution for a portable but on our desktops it seems to work as a stopgap to just keep the wireless card from entering some power management state.
Code:
ping -i 0.2 10.0.0.1 > /dev/null
